To all whom it 'may concern: y

Beit known that l, Cmir'rov M. liunr., a ,citizen of the United States oi Ant t, residing at Jeannette, in the county ot cstmoreland and State el Pennsylvania, have invented certain new and uselul `lniprove- Inents in hllining-Cars, et' whichthe following is a specification, reference being had therein to the accompanying drawing.

This invention relates to mining cars', and the invention has for its object to provide a car with novel means for conveying a quantityT et fresh air into the galleries and 'pits ol a mine, whereby the workmen or niine rs eniployed within the mine can be furnis ed wi fresh air, instead of entirely inhaling the gases and impure air ot' a rnine. To this end, i, provide a mining er pit car with an air reservoir er tank, which is charged each tinie the car is unloaded. ln coniiieetion with the tank l use a safety valve and an automatic ally actuated discharge valve, the valve being operated when the gate ol the pit car is closed at the mining or excavating point ot a mine.

The detail construction entering into niy invention will be hereinafter more lully described and then specifically pointed out in the appended clainis, and. referring to the drawing forming part el this specitcatien,

like numerals et reference designate corre spring 16 norinally maintains the discharge spending parts throughout the several views, in which Figure l is a side elevation et a car corn structed in accordance with my invention, and Fig. 2 is a horizontal sectional view voli the tank carried by a car.

In the accompanying drawing, l have illustrated a mining or pit car .1 supported upon a conventional terni et truck The car l isprovided with a pivoted end gate IP., whereby when the car is'placed upon a tipple coal eanbe discharged troni the end ot the car.

My invention resides in mounting beneath a lipplc it can be char 'ed with air, the air being retained within the tank by the check .i provide the pipo 5 with a saletv v el, said valve discharging airlroni the tank, when the contents ot the saine has been Gg subjected to a p redeterinined pressure.

in order to discharge the air within the niine, when the car has reached its destina-A tion, l provide the side ot the tank opposite the inlet pipe with a discharge valve-9, the G5 valve stern 10 ot said valve being provided with a crank arni 1l, the end ot said arni being` connected to an actuating rod 12 slidably mounted in. brackets lil, carried by the side ol the ear l. The end of the actuating rod 12 is provided with an adjustable sleeve 15, this sleeve boing adjusted to engage the gate 3. Upon the rod 12 between the brackets l-il is mounted a coiled spring 1li, said spring being connected to said rod 75 and cinployed for holding the sleeve 15 nornially in engagement with the gate 3. ln connection with the discharge valve 9, l ein- 'ploy a sound deadener 17 ot a conventional lorin, to prevent the escaping air from inak- S0 ing a noise within the niine.

lt is the coinnion practice, after discharg` ing the contents of a ,a'r at a tipple, to allow the gate 3 to reniaiu open until the car reaches its destination within a inine, and 8.; when the gate 3 is in an open position, the

valve E) in a closed position, whereby the ta1 t fl at the tipple can be charged with air. After the car has reached its destination gg within the niine, and the miner closes the gate 3, the actuating rod 12 will open the discharge valve 9 allowing the compressed air within the tank Llto gradually escape into the inine through the sound deadener 17.

lt will be seen that .my invention ainis to i inprovethe atmospheric conditions within a niine and provide better' ventilation for workmen engaged in quarrying minerals.

ll'l'y invention is extremely siniple in con- 19;.

struction, and ordinary niine cars can be easily and quickly equipped with an air tank.

. llaving now described rny invention what l' claim as new, is :im

1. The combination with a mining ear having a hinged end gate, ol an air tank mounted beneath said car7 an air inlet pipe carried by said tank and having a check valve, a sal'cty valve carried by said pipes, a disl;

`a s rino held actuatinO' rod and a sleeve ad- C D I charge Valve carried by said tank and having justably mounted upon the end of said rod for engaging said gate.

2. The combination With a mining cai' having a hinged gate, of anV air tank located beneath said car, an inlet pipe carried by said tank, a safety Valve carried by said pipe, a discharge valve carried by said tank, a Valve actuating rod movably mounted upon said car, an adjustable sleeve carried by said rod for engaging said gate, and means to noimally maintain said Valve in a closed position.

3. The combination With a mining cai' having a hinged gate, of an air tank carried by said cai' and having an inlet pipe, a dis- 1 chalge valve carried by said tank, means to normally hold said Valve in a closed position, anld means actuated by said gate to open said va ve.

4. The combination With a car iovided with a hinged end gate, of an air tan i carried by said car and having an air inlet, and means carried by the car and automatically 25 operated by the closing of said end 'ate to permit the escape of air from said taiilk.

ln testimony Wheieof l affix my signature in the presence of two Witnesses.
